REVERB Pages
Reverb is a multitude of echoes that are spaced so close together that, to human
ears, seem as a single continuous sound. These echoes gradually decrease in intensity
until they are ultimately absorbed by the boundaries and obstacles within a room. As
the sound waves from the sound source strike the boundaries of a room, a portion of the
energy is reflected away from the obstacle while another portion is absorbed into it —
thereby causing both the continuance of sound as well as the decaying or “dying out”
of the sound.
Reverb Types
The Prophesy provides the following types of reverb:
• The Plate reverb type simulates an artificial method of producing reverberation,
popular in the early years of recording, which involved using a fairly large, but
very thin, metal plate suspended at its four corners by steel wires under
tension. This metal plate becomes excited by a driver unit (similar to a dynamic
speaker without the diaphragm) and the resulting reverberation is picked up by
contact microphones.
The Prophesy offers two Plate reverb types which reflect the most common
plate characteristics. This type of reverb is often used on drum and vocal tracks.
• Room reverb effects simulate various rooms of different sizes and surfaces. For
example, a room which is made up of primarily hardened surfaces (such as tile
or hard wood) will generate reflections containing much more high frequency
information than one which is made up of softer surfaces (such as thick
carpeting). The Room reverb effects provided by the Prophesy can generate
virtually any imaginable room setting via highly efficient and adjustable reverb
parameters.
• Hall reverb simulates the reverberation characteristics of a very large room with
a high ceiling. Reflections in a hall are much longer than a typical room, as the
length of time it takes for the sound waves to travel from one surface to the
next is greatly increased.
• Stadium reverb simulates the characteristics of a large stadium or arena and
should be used with large amounts of predelay and high frequency damping.
• Dual reverb is unique in that it allows for the left and right channels to be
processed independently of one another. For example, the predelay for the left
channel can be set at 100mS while the Predelay for the right channel can be
set at 200mS. This results in reverb output from the left channel 100mS before
reverb is output from the right channel.
